The Wine architecture is loosely modelled after the architecture of
Windows itself. In Windows, messages are usually switched via the kernel,
so yes, a wineserver call will be involved in that as the wineserver
typically represents the Windows kernel.

You can see the message queue/switch code in server/queue.c

Useful debug channels here are +message and +msg, which give different
views onto message flow. Be careful, in complex GUI apps they can generate
large amounts of data.
